Yellowstone also sits on top of an ancient super-volcano, which scientists believe last erupted about 640,000 years ago, covering most of North America in ash. It also sits on the Continental Divide, with water from its numerous lakes and springs draining towards opposite sides of the United States. The Snake River and Yellowstone River both have origins within the park; the Snake River flows westward towards the Pacific Ocean, and the Yellowstone River flows eastward towards the Atlantic Ocean.  

The Grand Canyon of the Yellowstone is one of nature's natural wonders. At 900 feet deep and a half-mile wide in certain spots, it features cascading waterfalls with brightly colored red and yellow walls; a result of geothermal and chemical reactions to the iron in the rock.

Yellowstone is a powerful, beautiful, priceless national resource that everyone should see. Words and descriptions only go so far, ultimately, Yellowstone begs to be experienced, explored, and discovered.
